My Number

My number: Indivisual Number for taxation and social security

My number system is used for identifying a specific individual in administrative procedures. Information linkage of administrative agencies makes it possible to omit documents in various administrative procedures. The card can also be used for identity verification at private services.

After entering Japan, you will be issued a My Number when you register your address at the local city (ward) office.
